A South Florida community is mourning the loss of a beloved teacher as police search for the person who gunned her down outside a preschool in northwest Miami-Dade.

Michelle Wilcox, a mother and teacher, died Wednesday apparently while trying to retrieve her mail. An argument inside a residence escalated and moved outside, where the 33-year-old was shot as she tried to run away, police said.

Even though the whole thing was caught on camera by the neighboring preschool's security system, detectives have still not identified the shooter.

Wilcox's students arrived at school today and learned that their teacher was the woman who was gunned down in the northwest Miami Dade neighborhood.

"It feels so surreal and my heart feels tarnished right now because she was such a good person," student Shir'niyaa Charles said. "It's just not fair. One minute you're here and the next minute you're gone."

The shooting, which police charactarized as a deadly domestic dispute, happened Wednesday afternoon just outside a daycare on northwest 119th Street and 22nd Court. Parents scrambled to pick up their children while Wilcox's family huddled around the scene.

"I can't even express how I'm feeling at this point," one coworker said. "We had a personal relationship as well as a business relationship and she didn't deserve it."

Wilcox was an elementary teacher at Center of Life Academy in downtown Miami, inside the Miami Rescue Mission. She also helped students get ready to go to college.

'"Anything you asked for, she would do it," Charles said. "She would go out of her way just to do it for you. She was just so sweet and full of life."

Police say the shooter was seen fleeing the scene in a white sedan. If you have any information call Crime Stoppers at 305-471-TIPS
